dQMPRESSION-TOP FOR DYE-VATS.

SPECIFICATION forming part of Letters Patent No. 780,400, dated January17; 1905.

Application filed August 1, 1904. Serial N- 219,097.

I from pressure during the dyeing or Washing operation.

A further object of the invention is to provide a plate of the characterset'forth which can be easily and quickly removed from the 2 machine.

The invention .has for its further object to construct a compression topor closure plate for dyeing machines which shall. be simple inconstruction, strong, durable, efficient in its 2 5 use, andcomparatively inexpensive to manufacture.

To these ends the invention consists of the novel combination,construction, and arrangement of parts hereinafter more specifically 3described, illustrated in the accompanying drawings, and particularlypointed out in the claims hereunto appended.

In describing the invention in detail reference is had to theaccompanying drawings,

I forming a part of this specification, in which- Figure 1 is a top planview of the plate, and Fig. 2 is a transverse sectional view on line a:w of Fig. 1. 1

Like reference characters denote like parts 4 throughout both views.

Referring to the accompanying drawings, 1 denotes a plate shown circular1n contour,

but any preferred shape maybe employed,

and which is adapted to close and operate in a dye-vat and rest upon thematerial to be dyed. The plate 1 is'provided with a series of openingsor perforations 2 to permit of the passage of dye liquor therethrough.Se-

perforation 7, through which 'made fast to the truss-irons 5.

cured to the upper face of the plate 1 and arranged near the edgethereof is a peripheral 5 0 angle-iron 3. This angle-iron has one of itsarms extending vertically from the upper face of the plate 1 and itsother arm extending toward the edge thereof and serves as areinforcement for said edge. To strengthen the plate 1, I provide aseries of radially-extending reinforcing members, preferably in the formof truss-braces, which will now be described. These reinforcing membersconsist of a number of truss-irons 5 of a length approximately equal tothe diameter of the plate 1 and are bent at their middle into V shape,

thus having their Wide portions at the angle.

The ends of the V-shaped irons are bent toward each other to form lugs6. 5

The plate 1 is provided at its center with a projects a bolt 8, havingan enlarged head 9. The trussirons 5 are arranged upon the upper face ofthe plate 1, with their angular 7 portions so arranged as to formanopening at the center of the plate, so that their arms will extendradially therefrom. The lugs 6 will thus rest against the vertical armof the peripheral angle-iron 3, to which they are secured by means ofbolts or rivets.

The truss-irons 5 when secured to thplate 1 are adapted to abut againsteach other that is to say, one arm of each iron is adapted to abutagainst an arm of theadjacent iron. A washer 10 is placed upon the freeend of the bolt 8 and the angular portions of the truss-irons 5 andcloses the opening formed by the angles of the irons, and the saidwasher 10 is connected to each of the truss-irons 5 5 through the mediumof a bolt 10. These bolts 10 are secured to their respective trussironthrough the medium of the holdfast de, vices 10, extending through thebolts 10 and arrangement the plate is reinforced at the center thereof.A nut 11 is screwed upon the free end of said bolt and engages theWasherto securely clamp the angular portions ofthe truss-irons 5 to theplate 1. .To secure the abutting arms of the truss-irons together and Bysuch an 9 to the upper face of the plate 1, angle-irons 12 are provided.These angle-irons 12 are arranged on one side of the abuttingradiallyextending arms of the truss-irons 5, preferably opposite oneanother, and have one of their arms secured to the upper face of theplate 1 by rivets or bolts extending through both the arm of theangle-irons and the plate 1. The angle-irons 12 are further secured tothe radial arms of the truss-irons 5 by means of rivets or boltsextending therethrough. Additional holdfast devices are employed, ifdesired, to assist in securing the abutting arms of the truss-ironstogether, and these holdfast devices are indicated by the referencecharacter 12.

Yokes, eyes, or other suitable devices 13 are secured at intervals tothe upper face of the plate 1, to which lifting-chains 14, connected inturn to a ring 15, are secured in order that the plate may be liftedfrom the vat when the dyeing or washing operation is completed.

It will thus be evident that when the top plate, as above described, isplaced in a dyevat and pressure is applied thereto for compressing thematerial to be dyed in the dye- Vat the peripheral angle-iron 3 Willeffectually prevent the edge of the top plate from bending or buckling,and the body of the plate will be strengthened and prevented frombending or buckling by the truss-irons 5.

In describing my invention I have described a top plate adapted to beused in a dye-vat which is circular in form; but it is to be understoodthat my top plate may be square, hexagonal, or of any other contour,according to the shape of the dye-vat in which it is intended to beused.

It is thought that the many ad vantages of the improved compression topor closure plate can be readily understood from the forego ingdescription, taken in connection with the accompanying drawings, and itwill, furthermore, be evident that changes, variations, andmodifications can be resorted to without departing from the spirit ofthe invention or sacrificing any of its advantages, and I therefore donot wish to restrict myself to the details of construction hereinbeforedescribed and as shown in the accompanying drawings, but reserve theright to make such changes, variations, and modifications as comeproperly within the scope of the protection prayed.
